Emergency Generator Hire for Construction Sites

When power fails on a construction site, work stops immediately. Equipment shuts down, deadlines slip, and safety risks increase across the entire project.

SGH provides rapid-response emergency generator hire for construction sites across Australia. With fast dispatch from local depots, we deliver and install generators quickly to keep your site powered and your team working.

Whether it’s an unexpected outage, equipment failure, or backup system issue, our team is available 24/7 to restore power and minimise disruption.

Emergency Power

When Do You Need Emergency Power on a Construction Site?

  • Temporary power systems fail

  • Backup generators break down during critical work

Choose the Right Power Solution for Your Site

Not sure which generator suits your project? Here’s what to think about before you hire:

Request a Generator Consultation
  • POWER OUTPUT
    What’s on site? Power tools, welding equipment, lighting towers — calculate your load to avoid downtime.
  • PORTABILITY NEEDS
    Need to move your generator between job sites? Go for trailer-mounted or portable models for flexibility.
  • FUEL TYPE
    Diesel is ideal for long-term efficiency. Petrol works well for light-duty or short-term needs.
  • COMPLIANCE & SAFETY
    Ensure the generator meets site regulations for emissions, noise, and safety testing. We’ve got you covered.

What size generator do I need for a construction site?

It depends on what you’re powering — tools, lighting, machinery. SGH will recommend the right kVA size based on your needs.

What type of generators are best for construction sites?

Diesel generators are the go-to for durability and fuel savings, while portable options are ideal for small tools and flexible use.

We also supply generators for many other applications, with solutions tailored to different industries and power needs.

What happens if power fails on a construction site?

Power loss can stop machinery, delay work, and create safety risks. Emergency generators provide immediate backup power to keep operations running and reduce downtime.

How fast can emergency generators be delivered to a construction site?

SGH can dispatch and install generators within hours depending on your location and site requirements, with nationwide support available.

Do you offer servicing for hired generators?

Absolutely. We handle all maintenance, repairs, and safety checks — even during your rental period.

Can I buy parts for my construction generator?

Yes — SGH stocks filters, batteries, tanks, and more. Fast delivery, even if you didn’t rent from us. Check out our parts page here.
